The Musical Instrument Digital Interface, or MIDI, turns 30 this week. While it's used across devices and mediums, for a long time it was crucial to your experience with video games, as it was a popular way of getting electronic music stored on game cartridges and discs, especially in the 1990s.

Everyone will have their favourite tracks or games that made use of MIDI music, but for me, it's old Lucasarts titles from the 90s, which made use of a revolutionary technology (for the time) called iMUSE, which was able to organically adjust a game's soundtrack based on the events taking place, rather than simply play tracks at pre-determined times.
